LIFT-MAST DESIGN OF MOBILE ANTENNA INSTALLATION Russian patent published in 2009 - IPC H01Q1/08 

FIELD: radio engineering.

SUBSTANCE: invention is related to antenna engineering, in particular to mobile antenna installations. In device comprising foundation, telescopic lifting mast mounted on foundation, support platform with antenna, according to invention, lifting telescopic mast is arranged with electromechanical drive. Mast body is fixed in Cardan suspension, comprising external and internal frames arranged with the possibility of rotation. Mast body is rigidly connected to internal frame and is arranged with its longitudinal axis perpendicularly to plane created with axes of Cardan suspension rotation. Along axes of Cardan suspension rotation there are drives of platform horizontalising installed, being electrically connected to detector of horizon fixed on mast. Support platform comprises fixed part, rigidly connected to end step of telescopic mast, and movable part, connected to fixed part of platform by means of axis of rotation with the possibility of their mutual turn, at the same time drive of platform rotation is installed along axis of platform movable part rotation. Antenna is located on movable part of support platform so that in working position antenna is located above mast, and in transport position - parallel to mast body.

EFFECT: development of compact device, providing for the possibility of fast unfolding-folding of antenna with horizontalising system independent on chassis.
